Rock Krawler 2021+ Jeep Wrangler JLU 4DR (4XE) 4.5in X Factor Coilover System

The 4.5-inch X Factor Coilover System from Rock Krawler uses 2.5-inch diameter, triple-bypass coilovers to give your 2021+ Jeep Wrangler JLU 4-door (including the 4XE model) a significant boost in off-road capability. These coilovers are designed to provide a substantial increase in wheel travel, allowing your tires to maintain contact with the terrain over rough obstacles. The triple-bypass design allows for independent control of damping forces at different points in the suspension stroke, offering improved control and comfort whether you're crawling over rocks or cruising down the highway.

This system is built around Rock Krawler's well-known X Factor long-arm suspension geometry, which is engineered to correct caster and provide a more stable ride at higher speeds. The kit includes front and rear long-arm brackets, adjustable control arms, and sway bar disconnects, all designed to work in harmony with the coilovers. The control arms are made from solid 1.75-inch diameter DOM (Drawn Over Mandrel) tubing, known for its strength and resistance to bending. The coilovers themselves feature high-quality seals and a robust construction to handle demanding off-road conditions.

Installation of this system will require modifications to your Jeep's frame and suspension mounting points, and it is recommended to have a professional mechanic perform the installation. The kit is designed to provide a 4.5-inch lift, accommodating larger tires and improving ground clearance. You'll also want to ensure you have appropriate shocks and potentially other supporting modifications to fully benefit from the increased travel and corrected geometry.
